FIGURE 2-7: HI TECH INSTALL CONFIRMATION
16. The MPLAB
®
Tools Install Shield Wizard Complete window should soon open
and prompt the user to restart the computer before using the software. To begin
using the tools, select the Yes, I want to restart my computer radio button and
click Finish to end the installation process and restart the computer.
Following restart, the user will be given the option to view a variety of documentation.
To view a document, simply highlight and click View Selected File.
The MPLAB
®
IDE and HI-TECH C
®
PRO for the PIC10/12/16 MCU Family Lite Mode
Compiler are now both installed and ready to use. The user is now ready to complete
the labs included in this user’s guide.
2.5 INSTALLING THE INCLUDED LAB FILES
The PICDEM™ Lab Development Kit CD-ROM includes a .zip file called
PICDEM_Lab.zip. This file provides a location for the user to save any projects
created while completing the labs in this user's guide and contains solutions for each
lab in a folder labeled solution. To install this folder, simply extract the contents of
the .zip file to the C:\ directory.
Note: A comprehensive introduction to the “HI-TECH C
®
PRO for the
PIC10/12/16 MCU Family Lite Mode Compiler Tutorial” (DS41322) is
provided on the accompanying CD-ROM.
Note: Lab folders must be installed to the C:\ to be used by the MPLAB IDE.
